The present application claims the priority to a Chinese patent application No. 201710323942.7 filed with the China National Intellectual Property Administration on May 8, 2017 and entitled “a method and apparatus for displaying a picture”, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present application relates to the field of computer technology, and in particular to a method and apparatus for displaying a picture.

BACKGROUND

Before displaying multiple pictures of different sizes, it is necessary to determine the size of a container corresponding to each picture and the position of the container on a display interface, that is, the layout of the container on the display interface. In the prior art, the above layout is generally achieved in waterfall layout method. The waterfall layout method is a layout method in which containers for a plurality of pictures are arranged from top to bottom in a plurality of columns in a fixed area.

The existing waterfall layout method displays pictures after arranging the pictures in columns with equal width, and specifically includes: determining a target width of a container corresponding to each picture according to a width of a display interface, a preset number n of columns, and a preset container gap; determining, for each container, a target height of the container according to the target width and an aspect ratio of a picture corresponding to the container; dividing the containers into n groups such that a difference between the sum of target heights of containers in one group and the sum of target heights of containers in any of the other groups is minimized, which may be called a minimum value; placing containers in a same group into a same column to complete the layout; and finally displaying a corresponding picture in each container.

In the existing waterfall layout method, n groups correspond to n columns. The minimum differences among the sums of target heights of the n groups result in minimum height differences among the displayed columns. However, in general, the minimum difference is not “0”, which means that there is a height difference between the displayed columns, as shown in FIG. 1, so that the displayed pictures are not regular, resulting in a problem of the poor display effect of the pictures.

DETAILED DESCRIPTION OF THE INVENTION

In order to make the objectives, technical solutions, and advantages of the present application clearer and more understandable, the present application will be described in more detail below with reference to the appended drawings and embodiments. Obviously, the described embodiments are only some, and not all, of the embodiments of the present application. All other embodiments obtained based on the embodiments of the present application by those skilled in the art without any creative efforts fall into the scope of protection defined by the present application.

Embodiments of the present application disclose a method and apparatus for displaying a picture, which will be described hereinafter in detail.

A method for displaying a picture according to an embodiment of the present application may be applied to an electronic device, which may be a laptop, a tablet computer, a desktop computer, a smart phone, or the like. Specifically, the method for displaying a picture provided by the embodiment of the present application is applied to a client software running on an electronic device, and the software may be a dedicated picture browser. Further, the method may also be applied to a function plug-in of the client software, for example, a function plug-in of a web browser, a function plug-in of a camera, a function plug-in of a picture processor, and the like.

As shown in FIG. 2, the method for displaying a picture provided by an embodiment of the present application includes S201-S206.

S201: obtaining n columns of containers, wherein n is a preset number of columns of containers, and original widths of containers in any one of the n columns of containers are equal.

The heights of the n columns of containers may not be equal. In order to display the pictures corresponding to the containers more regularly, it is necessary to adjust the height of each container column. Therefore, the n columns of containers are obtained for adjustment. A container column is any one of the n columns of containers. In the embodiment of the present application, the number n of columns is not limited. For example, n may be 2, 3, 4, or the like. The container in the embodiment of the present application is a component for displaying a picture.

In one implementation, the obtained n columns of containers may be generated by means of waterfall layout with columns of equal width, and may be generated in other manners, which is not specifically limited in the embodiment of the present application.

It should be noted that the original widths of the containers in any one column of the obtained n columns of containers are equal, that is, the widths of containers in the same column of containers are equal. The widths of containers in different columns of containers may be equal or not equal, which is not limited in the embodiment of the present application.

Optionally, when the widths of containers in different columns of containers are equal, the width of each column may be w_(e):

${w_{e} = \frac{W - {\left( {n - 1} \right)s}}{n}},$

wherein W is the width of a display interface, and s is a preset container gap. Accordingly, when the widths of containers of the n columns of containers are equal, the height of each container may be h_(e):

${h_{e} = {w_{e} \times \frac{h_{p}}{w_{p}}}},$

wherein h_(p) is the height of a picture corresponding to the container, and w_(p) is the width of the picture corresponding to the container.

Optionally, in generating the n columns of containers, a container included in each of the n columns of containers may be determined by grouping containers via dynamic programming, such that the difference between the sum of heights of containers in each group and the sum of heights of containers in any one of other groups is smallest, and determining containers in the same group as containers in the same column. Preferably, in order to simplify the generation of the n columns of containers, a container for which a column is not determined can also be inserted into a column of containers with the smallest column height, to determine containers included in each column.

In an implementation, the process of obtaining the n columns of containers may include: dividing multiple containers into N columns by means of dynamic programming grouping. Specifically, the principle behind dividing multiple containers into N columns is to minimize the difference between the sum of heights of containers included in each column and the sum of heights of containers included in any one of other columns. In another implementation, in order to simplify the process of obtaining the n columns of containers, the process of obtaining the n columns of containers may include: inserting a container for which a column is not determined into a current column with the smallest column height, so as to determine containers included in each column. For example, it is necessary to determine a column to which a container A belongs. The current height of a container column 1 is 19.00 cm, the current height of a container column 2 is 18.91 cm, the current height of a container column 3 is 19.11 cm, and the current height of a container column 4 is 18.32 cm. At this time, the height of the container column 4 is smallest, and thus the container A is inserted into the container column 4. At present, it is necessary to determine a column to which a container B belongs. The current height of the container column 1 is 19.00 cm, the current height of the container column 2 is 18.91 cm, the current height of the container column 3 is 19.11 cm, and the current height of the container column 4 is 19.90 cm. At this time, the height of the container column 2 is smallest, and thus the container B is inserted into the container column 2, and so on, until all the containers to be inserted into the container columns are inserted into respective container columns.

S202: obtaining a height of each column of containers, and taking a maximum value of the obtained heights as a first height.

After the n columns of containers are obtained, the heights of the columns of containers are calculated and compared to obtain the highest height.

Specifically, the height of each column of containers may be the sum of the heights of all the containers in the column of containers and the gap between every two adjacent containers in the column of containers. Therefore, the height of each column of containers can be obtained based on the heights of the containers included in this column of containers and the preset container gap.

In an alternative implementation, a container is generally a regular rectangular shape, so the height of a column of containers can be obtained by calculating the difference between the upper left ordinate of the topmost container in the column of containers and the lower left ordinate of the lowest container in the column of containers.

Optionally, the heights of the columns of the containers can be compared. The highest height is selected as the first height, thereby obtaining the first height, that is, the height of the highest column of containers.

S203: for each target column of containers, determining a height increment of each container in the target column of containers according to a difference between a height of the target column of containers and the first height, and adjusting an ordinate of each container and a height of each container in the target column of containers according to the height increment of each container in the target column of containers, wherein the target column of containers is each column of containers in the n columns of containers other than a column of containers with the first height.

After the first height is obtained, the heights of the remaining columns of containers need to be adjusted to the first height. Therefore, it is necessary to calculate the difference between the height of each column of containers and the first height to obtain an adjustment value of each column of containers, so as to obtain a height increment of each container in the column of containers.

For one column of containers, height increments of different containers in the column of containers may be equal or may not be equal, which is described in detail below.

In case the height increments of containers in the same column of containers are equal, optionally, a height increment Δy of each container in each target column of containers is determined according to the following formula:

${{\Delta \; y} = \frac{\Delta \; h}{m}},$

wherein, Δh is a difference between a height of a target column of containers and the first height, and m is the number of containers in the target column of containers.

In case the height increments of containers in the same column of containers are not equal, optionally, a height increment of each container is calculated according to Δh and the ratio of the height of this container to the sum of the heights of all the containers in a column of containers in which this container is located.

After the height increments are obtained, the height of each container is increased according to the height increment corresponding to the container.

Since the heights of the containers have changed, it is necessary to adjust the ordinate of each container. In an alternative embodiment, the height change of each container in the same column of containers is equal. Thus, according to height increments of each column of containers, an ordinate of each container in the column is adjusted. Optionally, an ordinate of each target container in the column of containers is adjusted according to the following formula: y′=y+(p−1) Δy, wherein, y′ is an adjusted ordinate of a target container, y is an ordinate of the target container before adjustment, Δy is a height increment of the target container, and p is a sequence number of the target container, in order from top to bottom, in a column of containers in which the target container is located.

Optionally, an ordinate of a container may be adjusted by first adjusting an ordinate of a reference point of the container, and then adjusting ordinates of other points of the container. In the embodiment of the present application, the reference point may be any point of the container, for example, the upper left vertex of the container.

S204: for each column of containers, adjusting a width of each container in the column of containers according to a second height, a ratio of a height of the column of containers to the second height, a preset container gap, the number n of columns, and a width of a display interface, wherein the second height is a sum of heights of the n columns of containers.

After the height of each container that needs to be adjusted in height is increased, it is necessary to adjust the width of the container. In order to improve the regularity of the container, the widths of the containers in the same column of containers are adjusted to the same value. Due to the limited total width of the display interface, the widths of containers whose heights are increased cannot be increased by a corresponding value. Therefore, the adjusted width of each column of containers is determined according to the ratio of the height of each column of containers to the total height of the n columns of containers, and the adjusted width of a column of containers with a smaller height is a larger value.

That is to say, the height of each container that needs to be adjusted in height is adjusted. In other words, after the height of each container is increased, the width of the container also needs to be adjusted. In order to improve the regularity of the container, the widths of the containers in the same column of containers can be adjusted to the same value, that is, the adjusted widths of containers in the same column of containers are equal. In addition, due to the limited total width of the display interface, when the width of a container whose height is increased is adjusted, the width of the container cannot may be increased by a corresponding value. The increasing of the width of the container by a corresponding value may include: determining an increment of the container based on the height increment of the container and a ratio between the width and height of the container. In one case, the adjusted width of each column of containers can be determined based on the ratio of the height of each column of containers to the total height of the n columns of containers. It can be understood that for a column of containers whose height is adjusted, the heights of the containers included in the column of containers are all adjusted, that is, the heights are increased. In order to ensure the regularity of the containers, after the height of a container is increased, the width of the container also needs to be increased, that is, the width of a column of containers whose height is adjusted needs to be adjusted. At this time, due to the limited total width of the display interface, after the width of each column of containers is adjusted based on the method for displaying a picture provided by the embodiment of the present application, the adjusted width of a column of containers that has a smaller height before adjustment may be a larger value, that is, the adjusted width of this column of containers is larger than the adjusted width of a column of containers that has a height higher than this column of containers before adjustment.

Specifically, the width of each container in each column of containers may be adjusted according to the following formula:

${w = {\left( {1 - \frac{h}{h_{\alpha}}} \right) \times \left\lbrack {W - {\left( {n - 1} \right)s}} \right\rbrack}},$

wherein, w is the adjusted width of a container, h is the height of a column of containers in which the container is located, h_(a) is the second height, W is the width of the display interface, and s is the preset container gap.

S205: adjusting abscissas of containers in each column of containers according to the preset container gap and the adjusted widths of containers in the columns of containers.

Since the widths of containers in each column of containers have changed, it is necessary to adjust the abscissa of each container in each column of containers.

In an alternative implementation, according to an adjusted container width corresponding to a column of containers on the left of a currently adjusted column of containers, the abscissa of each container in the currently adjusted column of containers is determined.

Specifically, the abscissa of each container is adjusted according to the following formula:

${x = {{\left( {i - 1} \right)s} + {\sum\limits_{c = 1}^{i - 1}\; w_{c}}}},$

wherein, x is the adjusted abscissa of a container, i is a target sequence number of a column of containers that the container is located, in order from left to right, in the n columns of containers, and w_(c) is a width of a container in a column of containers with a sequence number c.

In an alternative embodiment, the abscissa of the container may be adjusted by first adjusting the abscissa of a reference point of the container and then adjusting the abscissas of other points of the container. Alternatively, the reference point of the container can be any point of the container, for example, the upper left vertex.

S206: displaying a corresponding picture in each container after the height, width, abscissa, and ordinate are adjusted.

After the width and height of a container are adjusted and the position of the container is determined, the picture corresponding to the container is displayed.

Since the width and height of the container are changed, the width and height of the picture corresponding to the container may be adjusted, so as to make the size of the picture close to the size of the adjusted container.

Optionally, a picture is adjusted by operations of:

calculating an adjusted height of a target picture corresponding to a reference container according to a height of the target picture and a first scaling ratio, wherein the first scaling ratio is a ratio of a width of the target picture to a width of the reference container, and the reference container is any container;

determining whether the adjusted height calculated is greater than the height of the reference container;

if the adjusted height calculated is greater than the height of the reference container, adjusting the width of the target picture to the width of the reference container, adjusting the height of the target picture to the adjusted height calculated, and displaying the adjusted target picture in the reference container; and

if the adjusted height calculated is not greater than the height of the reference container, adjusting the height of the target picture to the height of the reference container, calculating an adjusted width of the target picture according to the width of the target picture and a second scaling ratio, adjusting the width of the target picture to the adjusted width calculated and displaying the adjusted target picture in the reference container, wherein the second scaling ratio is a ratio of the height of the target picture to the height of the reference container.

Optionally, the adjusted height a′ of the target picture may be calculated by the following formula:

${a^{\prime} = {a \div \frac{b}{m}}},$

wherein,

$\frac{b}{m}$

is the first scaling ratio, b is the width of the target picture, m is the width of the container corresponding to the target picture, and a is the height of the target picture.

Optionally, the adjusted width b′ of the target picture may be calculated by the following formula:

${b^{\prime} = {b \div \frac{a}{n}}},$

wherein n is the height of the container corresponding to the target picture.

In the method for displaying a picture provided by the embodiments of the present application, each column of containers in the n columns of containers of unequal height is adjusted to a first height, such that the heights of the columns of containers are equal. In this way, the regularity of the arrangement of the n columns of containers is higher than that of the arrangement of containers in prior art, which allows the pictures to be displayed more regularly, thereby producing a beautiful display effect of the pictures.

It can be understood that height increments of containers in each column of containers mainly depend on the difference between the height of this column of containers and the height of the highest column of containers. When the difference is large, the height increment of each container in the column of containers is relatively large. On the contrary, the height increment of each container is relatively small. In order to make the height increment of each container meet a preset condition, the embodiment of the present application further includes:

determining whether the heights of the n columns of containers fluctuate within a preset range, and if yes, performing the step of taking the maximum value of the obtained heights as the first height.

Optionally, the preset range can be set to a small value. When the heights of the n columns of containers fluctuate within a small range, the difference between the height of each column of containers and the height of the highest column of containers may be in a small range, so that each container has a smaller height increment, which helps to ensure the regularity of the displayed pictures, and makes the adjusted width and height of the containers close to the sizes of the pictures.

In one implementation, the preset range may be set to be a small value, that is, the heights of the n columns of containers are limited to fluctuate within a small range. When the heights of the n columns of containers fluctuate within a small range, the difference between the height of each column of containers and the height of the highest column of containers may be in a small range, so that each container has a smaller height increment, which helps to ensure the regularity of the displayed pictures, and makes the adjusted width and height of the containers close to the sizes of the pictures.

In order to explain the method for displaying a picture according to the embodiment of the present application more clearly, the following detailed description will be given by way of examples.

For example, two container columns of equal width as shown in FIG. 1 are obtained. Numbers 1-5 in FIG. 1 represent five containers respectively. A container 1, a container 3, and a container 5 constitute a column of containers A, and a container 2 and a container 4 constitute another column of containers B. It can be known through calculation that the column of containers A is the highest column in the two columns, therefore the height of the column of containers B needs to be adjusted to the height of the column of containers A. Specifically, a height difference between the two columns A and B is calculated, and the difference is divided by the number of containers in the column B, that is, divided by 2. Thus, height increments of the container 2 and the container 4 are obtained, and the heights of the container 2 and container 4 are increased by the corresponding height increments. As the height of the container 2 increases, an ordinate of a reference point of the container 4 is increased. Since the heights of the containers in the column B are increased, it is necessary to adjust the widths of the containers in the two columns, so as to ensure the minimal change in the aspect ratio of the containers in the column B. Specifically, the sum of the heights of the two columns A and B is calculated, and the ratios of the heights of the two columns A and B to the sum of the heights are respectively obtained. Then, two widths are obtained by multiplying the above two ratios by a value obtained by a display width minus a container gap. It can be understood that one of the widths is smaller than the current width and the other width is larger than the current width. Since the heights of the containers in the column B are increased, the widths of the containers in the column B are adjusted to a width greater than the current width, and the widths of the containers in the column A are adjusted to a width smaller than the current width. Then, as the widths of the containers in the column A are changed, it is necessary to adjust the abscissas of the containers in the column B. Specifically, the adjusted width of container of the column A can be added to the container gap to obtain the abscissas of the container 2 and container 4 in the column B. Finally, corresponding pictures are displayed in the adjusted containers, as shown in FIG. 3.
